The scattering of light by liquid crystals is primarily a result of orientation fluctuations and is formally similar to the scattering by solid crystalline polymers. Some experimental results for the photographic scattering of mesophases of cholesteryl myristate are presented. The patterns for the cholesteric state are similar to those for spherulitic polymers and are analyzed using the theory for scattering from media exhibiting non-random orientation correlations. As a result of the light scattering studies it may be shown that the cholesteric state is characterized by disc-like correlations, while the smectic state and solid cholesteryl myristate both show random orientation correlations.
